Typical of New England mills, the Collins Company axe factory was sited on a river (the Farmington), and their production was powered by utilizing the water's strength to turn turbines and power machines. The numerous old buildings ramble along the riverbanks intertwined by an intricate maze of sluices that run throughout the site. The company closed its doors in 1966, but the factory buildings are now home to an eclectic and constantly changing mixture of tenants, including antique sellers, offices, artists' studios, woodworkers and a dance studio. The ambiance of Main Street reflects period architecture with ornate details from the start of the 20th century.[citation needed]

Collinsville is located directly on the Farmington River, and is a common place for people to walk and bike to, due to its convenient location along the Rails to Trails path. There are many cultural attractions in this town center, including LaSalle Restaurant, where customers are allowed to leave before paying, and return when they have finished eating, to pay.[citation needed] Frequently on Sundays and other occasions, there are live music demonstrations in the parking lot outside.

The Canton Historical Museum is located in a former Collins Company factory building built in 1865. Originally constructed to finish and assemble agricultural plows, the building was converted in 1924 to a recreational facility for its employees. Fred Widen, a pattern maker for the company, used a portion of the building for his large collection of Collins memorabilia. Today, the Canton Historical Society owns the 14,000+ sq. ft. building and has a large assortment of Collins Tools, as well as many Victorian items, a general store, farm/agricultural equipment, children's toys, looms, and a Bridal Parlor featuring wedding dresses worn by Canton residents from the late 1800s. Also of interest, are several Regina music boxes, a large pump fire engine, used by the Collins Company, an Edison phonograph and Edison fans. Upstairs, the Farmington Valley Railroad Society operates a railroad diorama of the village of Collinsville around the start of the 20th century.

A research and genealogical library containing thousands of documents and photographs related to Canton and Collinsville history is also located upstairs, including black and white photos of the 1955 flood. Information about local cemeteries in Canton and Collinsville are available in the library. The museum covers three floors with limited handicap accessibility, but plans are underway to make the building more accessible in the future.

In the 19th century, a Collinsville butcher feuded with his neighbor.[7] To spite his neighbor, the butcher built between their adjoining houses a narrow, two-story structure with windows covered by Venetian blinds.[7] The wooden building located between 23 and 25 River Street was the width of a standard stairway and allowed the butcher to block the sun to the neighbor's home and block the neighbor's view of the butcher's property at will.[7][8] The butcher's son got along with the family next door and eventually tore down the Collinsville Spite House.[7]
